OSS folks, looking for two recommendations, both relating to eink / ebook devices.
* Need ebook reader device recommendations, onto which I will replicate my entire library.
* Also need an eink pad, good for mathematical writing in particular. Should be hackable, as I may want to try some sort of OCR integration with some kind of ITP/computer algebra system some day.
Can be the same device or not, but OSS-friendless and ability to connect with an OSS laptop is a must.
